FBA FL DELTA Series

The FBA coupling is a one piece, all steel drive The FL is a two-piece flywheel coupling used The DELTA Series flexible coupling line iscoupling intended to be used with spline shafts on off-highway construction equipment such designed for use on diesel-driven hydrostaticonly in hydraulic pump applications. as skid steer loaders, aerial lifts, excavators, machinery and construction equipment for and many other mobile hydraulic applications. demanding applications on the latest tier Elastomeric grommets provide a steady Not only is the FL our oldest product line, it is engines. dampening effect to normal engine our most economical design with decades of vibrations, helping to minimize any side Cost effective, single-piece design proven success in the field. loading to the pump shaft incorporates a splined and hardened steel Easy installation, no positioning of hubs Consists of a glass reinforced nylon flywheel hub pre-assembled into glass-fiber reinforced Once the hydraulic pump is plugged into flange that will fit both SAE and metric flange one of our mounting plates or housings, the flywheels Elastomeric grommets provide a steady pump assembly can be blind fitted into the Mating hub is produced from sintered dampening effect to normal engine coupling hub steel and can be used on both splined and vibrations Pump spline lubrication is required straight shafts Design allows equipment with low inertia to Fits standard and non-standard SAE flywheel Considered a torsionally stiff design and operate below the critical speed range designs does not require lubrication Suited for accurately aligned drives that Can be used on applications up to 450HP Interchangeable to other popular coupling minimize misalignments brands Accommodates small angular, parallel, and axial misalignments typical to piloted flange connections Can achieve torque capacities of up to 6,130 IN-LBS nominally

NV Series Guard-Flex FHThe NV Series flexible coupling line is for use The Guard-Flex is a torsionally soft, vibration The FH is a coupling with progressiveon diesel-driven and hydrostatic machinery to dampening coupling with an in shear design characteristics where the dynamic torsionalprovide maximum vibration dampening from a that will offer protection to both our engine stiffness is enhanced with increasing couplingtorsionally soft coupling. and driven equipment when higher inertias are load. This type of coupling gives a distinct present. Ideal applications include rotary screw advantage in installations where a wide speed Single-piece design incorporates a cast iron compressors, centrifugal pumps, blowers, range is required, and where the torque hub and a steel back plate with molded rubber generators, and hydraulic pumps increases with speed. Acts as a mechanical fuse, providing protection and dampening for lower driven inertias Acts as a mechanical fuse in the event of an Relatively low torsional stiffness that places Works specifically with the Kubota Super overload condition the critical speed below the operational Mini Series and 05 Series engines, but also Designed to fail through the rubber and shear speed of the system accommodates standard SAE size flywheels Three elastomers are available from stock to Intended for higher inertia loads such as a from SAE 6.5 through SAE 10 provide the proper dampening and stiffness compressor, centrifugal pump, blower, and Accommodates small angular, parallel, and The Guard-Flex rubber is offered in 45, 55, generator axial misalignments typical to piloted flange and 65 shore A durometers Fit all SAE flywheels from SAE 7.5 through connections Incorporates axial, radial, and angular SAE 18 Suited for accurately aligned drives that misalignment to help reduce forces to the Variable durometer inserts can provide minimize misalignments driven equipment torque capacities up to 88,500 IN-LBS Can achieve torque capacities of up to 1,524 Fits applications with a SAE 7.5 through SAE IN-LBS nominally 11.5 flywheel, and is rated up to 82 HP
